IPC: G01R1/04
Filed: 1973-05-11
Abstract: 1464875 Multimeter SOLARTRON ELECTRONIC GROUP Ltd 1 May 1974 [11 May 1973] 22510/73 Heading G1U [Also in Divisions G3, G4 and G5] The housing of an electrical measuring instrument e.g. a multimeter or clock contains a liquid crystal display device 36, means 44, for admitting light into the interior of the housing and a reflector 48 for directing the light out through the device. In a digital multimeter light enters the housing through a frosted, reeded or opaline window 44 and is reflected to the device by a white member 48. Light may enter though an aperture and be directed by light guides. The arrangement avoids providing a light source powered by the battery 37. However for use in low ambient light conditions a lamp powered by a different battery and controlled by a photo-electric device may be provided. Alternatively a separate light source may be secured over the window 44. The multimeter includes an automatically controlled input alternator 22, anode selector circuit 24 and an analogue to digital converter 30 whose output is applied to an amplifier driving the display device. Elements 30, 34 may form an integrated circuit. The housing may alternatively contain a digital clock or counter/timer.

Patent GB-1490438-A (GB)
Title: Well flow control valve method and apparatus
IPC: E21B34/10
Filed: 1975-05-27
Abstract: 1490438 Wells &c. HYDRIL CO 27 May 1975 23126/75 Heading E1F A well flow control valve, e.g. a safety valve, includes a rotatable flow control element 36 which sealingly engages a valve seat which includes a resilient annular seal 40 and operating means which space the valve seat 40 from the control element 36 prior to rotating the control element 36. As described the flow control element 36 is a ball (Fig. 1B) which is engaged by eccentrically mounted pins 100 fixed to the valve housing and by lugs 56b of a control frame 56, downward movement of the control frame 56 thus rotating the ball 36 to its open position. The ball 36 engages an upper seat 42 formed at the lower end of an upper operating sleeve 104 and a lower seat including resilient seat 40 mounted in the upper end of a lower operating sleeve 52. A projection 52c on the sleeve 52 engages a slightly larger recess 56c in the central frame 56. The sleeves 52, 104 are urged upwardly by spring 64, 122 respectively to hold the ball 36 in its closed position. The ball 36 is moved to its open position by moving the sleeves 52, 104 downwardly. Sleeve 52 is moved downwardly by downward movement of either one of annular pistons 80 and 86. The space 96 between pistons 80, 86 is connected via ports 68d and 156b and passage 156 to a first control line L1 and the spaces above piston 80 and below piston 86 are connected to a second control line L2 (not shown). Thus an increase in pressure in one of the lines L1, L2 relative to the other will cause downward movement of one of the pistons 80, 86 and thus downward movement of the sleeve 52. The sleeve 104 is moved downwardly by pressure in the one of the lines L1, L2 by a similar arrangement including annular pistons 124, 126. In use downward movement of sleeve 52 moves the seat 40 away from the ball 36 and when the projection 52c engages the bottom of recess 56c moves the control frame 56 downwardly. This moves the ball 36 downwardly away from seat 42 and rotates it to its open position. Downward movement of sleeve 104 is delayed by well pressure acting on piston surface 104d of sleeve 104 until the ball 36 moves to its open position and permits well pressure to act via port 104b on surface 104a. The sleeve 104 then moves downwardly to engage the ball 36, moving it to its fully open position and seating it against seat 40. The above sequence is reversed when the valve is closed by the action of springs 64, 122 when pressure in line L1 or L2 is removed.

Title: Improvements in and relating to power operated means for closing vehicle doors
IPC: E05F15/56
Filed: 1921-09-05
Abstract: 189,860. Rowntree, H. Sept. 5, 1921. Operating and controlling doors pneumatically. -In pneumatic power-operated mechanism for closing vehicle doors of either the sliding or swing- ing type, means are provided permitting the doors. to be opened by hand and causing them to stop closing when they encounter an obstruction and to resume closing when the obstruction is removed, thus ensuring the safety of passengers. A series of doors may be closed from one operating position and the opening of one by a passenger or its stoppage by an obstruction will not affect the others. The Figure shows a single sliding door 1 secured to the back edge of which is a hollow rod 2 carrying a piston 3 sliding in a cylinder 4 which is supplied with pressure air at 5. Slow closure is obtained by a restricted passage for the air, and the front edge of the door is provided with a shoe 7 pivotally suspended from it by links 8 and abutting a rod 11 extending through the hollow piston-rod and carrying a valve 12 normally seating over a hole 13 in the piston. When the door meets an obstruction or is required to be opened the shoe is collapsed against the edge of the door, unseating the valve 12 and permitting the pressure air to escape through an opening 20 larger than the inlet so that the door may be opened. As soon as the shoe is allowed to fall back the valve will seat itself in the piston and closing will be completed. The apparatus may be adapted for swinging doors, the shoe 7 being replaced by a spring-pressed plate on the outer-side of the door near the edge, the cylinder 4 hinged to the car body and the hollow piston-rod 2 pivotally connected to the door. The spring- pressed plate acts through a bell-crank lever to open a valve in the piston-rod when an obstruction is encountered.
